Energy consumption data logger MacR6 E

MacR6 E energy consumption data logger with built-in IoT telemetry module for LTE Cat. M, NB-IoT, 2G

MacR6 E is an electricity data logger with an integrated telemetry module.

The main use of the device is to transmit information about recorded energy consumption and alarm conditions to the data collection system, enabling calculation of the energy consumption factor in the water supply system.

The logger is equipped with an integrated modem operating in NB-IoT, LTE Cat.M1, 2G technologies.

In addition, the device allows integration into a local BMS building management system and management of electricity consumption

  • Support for low-power LPWAN mobile data technologies: LTE Cat.M1 and NB-IoT
  • Standard commercially available D-size lithium battery, allowing for a 10-year service life
  • LCD display showing connection status, network level , battery status and power consumption logging
  • IEC 62056 optical interface for local Android configuration
  • Efficient data transmission in harsh environments through LPWAN technology support
  • Dedicated mobile app for device configuration and reading logged data
  • Optional built-in control outputs
